What are the primary sources of Medicaid data?
The primary data sources for Medicaid statistical data are the Medicaid Statistical Information System (MSIS), the Medicaid Analytic eXtract (MAX) files, and the CMS-64 reports. The following is a general explanation of these reports and the types of program and financial data collected from the states.
Why are there inconsistencies in Medicaid data?
Users of Medicaid data may note apparent inconsistencies which are primarily due to the difference in the information captured in MSIS , or the former HCFA-2082, versus CMS-64 reports. The most substantive difference is due to payments made to "disproportionate share hospitals." Disproportionate share hospitals receive higher Medicaid reimbursement than other hospitals because they treat a disproportionate share of Medicaid patients. States determine if hospitals meet the criteria to be considered a "disproportionate share hospital" and establish a formula used to calculate the amount of the payment, subject to certain minimum standards under the law. States claim the Federal match for payments to disproportionate share hospitals on the CMS-64. States combine this claim either with other inpatient hospital services claims or with mental health facility claims. However, payments to disproportionate share hospitals do not appear in MSIS since states directly reimburse these hospitals and there is no fee-for-service billing.
What is the difference between CMS 64 and MSIS?

Finally, national totals for the CMS-64 are different because they include other jurisdictions, such as the Northern Mariana Islands, and American Samoa.
